Fantasy basketball is a virtual sports game where participants act as owners and general managers, drafting real professional players (typically from the NBA, but also the WNBA or NCAA) and earning points based on their actual on-court statistics. The game's popularity surged after the success of Rotisserie League Baseball, aided by internet access to stats, and its legal status in the U.S. was largely settled following the 2018 Supreme Court ruling in Murphy v. NCAA, which allowed states to legalize sports betting—a decision that helped daily fantasy platforms like FanDuel (which the NBA invested in back in 2014) operate in 44 states by August 2022. Leagues are commonly played in two main formats: rotisserie, where teams are ranked and awarded points across statistical categories, and head-to-head, where teams compete in weekly matchups. Platforms like Yahoo! Sports use nine standard categories, including points, rebounds, assists, steals, blocks, three-pointers, field goal percentage, free throw percentage, and turnovers. For example, in a rotisserie league, the team with the most rebounds in a twelve-team league earns twelve points, the next earns eleven, and so on, while negative categories like turnovers award the most points to the team with the fewest. League organization can also vary in roster structure and category weighting, allowing for deep customization.
